Common questions
Why choose square tubes over round mailing tubes?
Square tubes eliminate rolling during transit, reducing packing time and product damage. They stack efficiently on pallets, saving warehouse space and shipping costs while providing protection for rolled items.
What is ECT-32-B corrugated material?
ECT-32-B is an edge crush test rating indicating 32 pounds per inch of corrugated strength. This material meets ISTA and shipping standards for medium-to-heavy-duty protection across domestic and international shipments.
Do these tubes require tools or adhesive to assemble?
No. These one-piece tubes fold together by hand without tape, glue, or equipment. Assembly takes seconds, making them ideal for high-volume shipping operations.
Are these tubes USPS and carrier-compliant?
Yes. These white corrugated square tubes meet UPS, FedEx, and USPS size and material requirements for Priority Mail and parcel shipping programs.
